Application June 10, 1955, Serial No. 514,438

1 Claim. (Cl. 312255) The present invention relates to a combination desk top and book box support and more particularly to a device of this character in which the book box is suspended from its top edge.

The primary object of the invention is to provide a combination support of the character described which eliminates the need for support ribs under the book box.

Another object of the invention is to provide a support of the above character which utilizes a cantilever support construction for supporting the desk top with no excessive resiliency.

A further object of the invention is to provide a support of this class which will be inexpensive to manufacture, simple to assemble, and exceedingly stable in use.

A still further object of the invention is to provide a device of the class described with means to permit a nicer vertical adjustment of the desk top with relation to the seat than possible in prior art structures.

Other objects and advantages will become apparent in the following specification when read in the light of the attached drawings, in which:

Figure 1 is a bottom plan view of the invention.

Figure 2 is a side elevation of the invention.

Figure 3 is an end elevation of the invention, with parts broken away.

Figure 4 is a cross-section taken on line 44 of Figure 1, looking in the direction of the arrows, with parts broken away.

Figure 5 is a cross-section taken on line 55 of Figure 1, looking in the direction of the arrows, with parts broken away.

Figure 6 is a cross-section taken on line 6-6 of Figure 1, looking in the direction of the arrows, with parts broken away.

Figure 7 is a cross-section taken on line 7-7 of Figures 2 and 3, looking in the direction of the arrows, with parts broken away.

Figure 8 is a cross-section taken on line 8-8 of Fig ure 2, looking in the direction of the arrows.

Now referring to the drawings in detail, wherein like reference numerals indicate like parts throughout the several figures, the reference numeral 10 indicates generally the combination cantilever desk top and book box support comprising the present invention. A generally rectangular framework 11 having a pair of parallel side members 12 and 13 which are connected by another pair of parallel members 14 and 15, is provided with a downwardly and forwardly extending support post 16 of generally O-shaped cross-section. The side members 12 and 2,831,744 i atented Apr. 22, 1958 13 are of generally inverted U-shape and are provided with a downwardly directed flange 17. Members 12 and 13 are provided with a cross-sectional U-shape to atford maximum strength and rigidity with a minimum of weight and cost. The member 15 has a generally T-shaped cross-section and is provided with'a downwardly directed flange 18, as disclosed in Figure 4. The member 14 has a generally inverted L-shaped configuration and is provided with a downwardly directed flange 19. The flanges 18 and 17 are expanded outwardly at one corner to form a brace 20 and a second brace 21 for the post 16. The flanges 17, 18 and 19 are perforated as at 22 to receive rivets 23.

A book box 24 having a generally parallelogram crosssection is adapted to be inserted within the flanges 17, 18 and 19 and may be secured thereto by rivets 23. The desk top (not shown) may be attached to the device when the book box 24 is in use by means of hinges of the type disclosed in applicants prior art Patent Number 2,254,133, issued August 26, 1941. In the event the device is to be used without the book box 24, the frame 10 is secured directly to a desk top by means of securing bolts (not shown).

The complete support of the desk top (not shown) and the book box 24 is by cantilever action, and the book box 24 is suspended from the framework without the necessity of using reinforcing ribs beneath the box 24 which would detract from the available leg room.

The cantilever action of the support provides strength while maintaining resiliency. The casting construction provides additional leg room without detracting from the overall strength and power of the device.

Having thus described the preferred embodiment of the invention, it should be understood that numerous modifications and structural adaptations may be resorted to without departing from the scope of the appended claim.

What is claimed is:

A combination desk top and book box support comprising an upright elongated member, said member having a C-shaped cross-section, a substantially rectangular open framework comprising a pair of U-shaped spaced apart end members and a connecting pair of side members joined thereto, one of said side members having a generally T-shaped configuration in cross-section, the other of said side members having a generally inverted L-shaped configuration in cross-section, means attaching said framework by one corner thereof to said upright member whereby said framework is supported by cantilever action by said upright member, a book box positioned within said framework, said book box having the configuration of a parallelogram in cross-section, and means suspending said book box from said framework.
